To all'wkom may concern.:

Be it known that I, CHARLES C. Mclar- 'rosH, a citizen of the UnitedStates, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented certain new and useful improvements inBrush Construction, of which the following is a specification.

The hereinafter described invention relates to improvements in brushes,and more particularly to that type of brush employed in fruit treatingapparatus, where it is desired to polish, brush or dry the fruit as thesame is conveyed from one machine, apparatus, or point to another, andthe invention has for its principal object to provide a rotatablestructure which is capable of conveying and brushing the fruit, andwhich is also adapted for the timing of the fruit to present the stemand blossom ends thereof for polishing, which is not the case with thedevices of this character now in use. Another and important object ofthe invenL tion is to provide a substantially circular brush having 'datbrushing faces and provided with a spirally disposed fruit convey ingbristle portion, the brush being constructed in such manner asto permitthe renewal of any face upon the same becoming worn, and withoutinterrupting the continuations of the spiral conveying bristle portion.

With the above mentioned and other objects in View, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the accompanying drawings, and pointed out inthe. appended claims; it being understood that various changes in theform, propor tion, size and minor details o f construction, within thescope of the claims, may be resorted to Without departing from thespirit or sacrificing any advantages of the inven tion.

To more fully comprehend the invention, reference lshould be had to theaccompany ing drawings, wherein for purposes of illustration, li havedisclosed brushes of octagonal shape in cross section, and in which-Figure 1 is a plan view of my improved brushes, arranged in parallelrelation to each other and disclosing the spirally disposed bristleportion for conveying the fruit.

Fig. 2 is an enlarged cross sectional view taken on line 2-2--Fig. l,disclosing the .vals substantially throughout their length are the brushsupporting members or cores 5, the peripheral edges of which are formedwith straight portions or faces as at 6, of

the same length, and said portions or faces extend at uniform angular"relation from each other, the core thus providing afigure having equalsides, an octagonal igure being disclosed in the drawings.

' Bristle backs 7 extend transversely of the supporting members or cores5, and are detachably secured thereto by screws 8 or other securingmeans, and the backs 7 are formed.

with inwardly beveled side edges `9, which permit of a tight jointbetween the abutting side edges of the backs.

Bristles l0 of any sin'table material are carried by the bristle backs 7and extend outwardly in a plane at right angles to the faces thereof,and the .outer ends thereof are cut to shape the brushing surfacesubstantially the same as the brush backs.

A spirally arranged tuft of bristles 1l eirtends the full length of thebrush backs, and the bristles forming the same project outwardly a.slight distance beyond the ends Y'of the bristles 10, and betwe'n thespiral ll,

the fruit to be polished is received, and is conveyed from one end ofthe rolls to the other.

rlihe bristles ofthe brushes are in substantially meeting relation forthe full length of the brushes, and the bristles at the .rnesting edgesA of the bristle backs of one brush are adapted, when the brushes arerotated., to Contact with the bristles-of the brush associated therewithintermediate the meeting edges of the brush backs, as in `Fig. 2, andvice versa. lirorn the above structure it will be apparent that when thefruit is deposited from the chute l2 'between the` rotating brushes,that edges .d of the bristles will contact with the fruit, toss the sameabout on the bristles so that all the surfaces of the fruit will bepresented to the bristles, and the fruit willr travel the length of thebrushes and be discharged therefrom through the chute 13. It will alsobe apparent that by providing the removable bristle backs, that anysection of the brushes that becomes worn may be readily replaced, andthat by projecting the spiral forming bristles beyond the main polishingor body bristles instead of forming the same by cutting a groove in thepolishing or body bristles as is now the custom, that a longer life isinsured the bristles.

Having thus described my invention what is claimed as new and is desiredto protect by Letters Patent is i l. A cleaning machine comprising asupporting frame, a pair of cleaning brushes rotatably mounted thereonwith their sur* faces in parallel meeting relation and providing betweenthem a fruit runway, the bristles of said brushes forming flat sidedlongitudinally extending circumferentially disposed brush faces ofuniform Width throughout their length, the eids of certain of thebristles of each of said brushes projecting beyond the others andforming 'a helical -`conveying rib having Hat faces to correspbnd withsaid brush faces, means for rotating said brushes to cause the fruitcarried between the same to be tossed about to present all surfacesthereof to the brush faces during its travel longitudinally thereof.

2. A cleaning machine comprising a pair of rotatable cleaning brushesdisposed in parallel meeting relation and providing between them a fruitrunway, each brush comprising a core, a plurality of bristle backsdetachably secured to the exterior thereof, bristles carried by saidbacks and forming with the bristles of the other brush backs flat sidedcircumferentially disposed brush faces of uniform width throughout theirlength, and the ends of certain of the bristles of each back projectingbeyond the others, and arranged in rows at an angle transversely acrossthe face of the brush backs, and when said backs are in position forminga helical conveying rib for each brush.

3. A cleaning machine comprising a frame,a pair of parallel spacedcleaning brushes rotatably mounted thereon, the bristles of said brushesforming flat 'sided circumferentially disposed brush faces of uniformwidth throughout theirlength, the ends of certain of the bristles ofeach of said brushes projecting beyond the others, and forming a helicalconveyingrib having fiat faces, the meeting edges of the faces of onebrush being disposed to contact with the .said projecting andintermediate faces of the ,opposite brush intermediate the i brushesrotatably mounted thereon, the

bristles of said brushes forming fiat sided circumferentially disposedbrush faces of uniform Width throughout their length, the ends ofcertain of the bristles of each of said brushes vprojecting beyond theothers and forming a helical conveying rib having flat faces, themeeting edges of the faces of one brush being disposed to contact withthe faces of the opposite brush intermediate the edges thereof, meansfor rotating said brushes at a uniform speed in opposite directions tocause the fruit carried between the same to be tossed first upwardlyonto one brush and then onto'the other )to present all surfaces thereofto the brush faces during its travel longitudinally thereof.

5. A brush for the purpose described comprising a body of non-circularcross-section presenting bristles constituting projecting parts disposedat intervals relative to intermediate parts, in combination with otherbristles extending outwardly beyond both parts to constitute a feedingelement. y

6. In a machine of the character described, coperating approximatelyhorizontally disposed rotatable brushes associated to form a support andrunway for the fruit to be treated, said brushes being of non-circularcross-section presenting relatively projecting parts adapted atintervals to engage and toss the fruit located in said runway,

Aand means for rotating said brushes.

`7. In a machine of the character scribed, coperating approximatelyhorizontally disposed rotatable brushes associated to form a support andrunway for the fruit to be treated, said brushes being of non-circularcross-section presenting relatively projecting parts adapted atintervals to engage and toss the fruit located in said runway, and meansfor rotating said brushes, the projecting parts of the opposite brushesbeing alternately disposed.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
